Abstract

1395391 Face masks VICKERS LTD 13 April 1973 [14 April 1972] 17416/72 Heading A5T [Also in Division F2] A medical face mask comprises a hollow body portion 1 arranged to be placed over the nose and mouth of a patient, and an inlet portion 5 communicating with the interior of the hollow body portion and including a tube 6 having at one end a gas, e.g. oxygen, inlet nozzle or injector 8 mounted therein, an air inlet device to permit a flow 16 of air to be drawn into the mask by the action of gas 15 passing through the nozzle 8, and outlet means 17 in the body portion 1 to permit exhaled etc air to leave the mask, the air inlet device being adjustable so that the air drawn into the mask by the injection of gas can be regulated according to a particular gas flow rate. The air inlet device comprises a pair of apertured members, one 7 fixed in the free end of the inlet portion, the other 9 rotatable relative to the member 7. Each member 7, 9 has a plurality of apertures so that rotation of the member 9 aligns particular apertures. The nozzle 8 extends through the aperture members 7, 9. A spring 10 holds the members in face-to-face contact. One member has a protrusion 12 on its contacting face, the protrusion riding over the contacting face of the other member during relative rotation and engaging selected apertures in the other member, to provide diluted air to vary the oxygen concentration to 50%, 60%, 70% or 80% at the respective settings. The mask is fitted to the patient by an elastic cord secured to holes (2) Fig 1 (not shown) in lugs 3 extending from the rim portion 4 surrounding the body portion 1 and facilitating close fitting of the mask to the patients' face. The body portion 1 is made of translucent, pliable, plastics material, and the tube 6 is rigid.
